, Specification of Letters Patent. i Patented Dec. 21, 1915.

Original application filed May s,'191 1, Serial to. 625,873. Renewed Novemberl l, 1914,.Seria1 No. 872,235. Divided and this application filed November 30, 1914. Serial No. 874,615.

To all whom it may concern:

Be it known that I, ART UR H. MEMM- LER, a citizen of the United States, residing at Monrovia, in the county of Los Angeles and State of California, have invented a new and useful Drawing-File', of which the following is a specification.

This invention relates to a file for holding drawings, tracings orv other sheet articles and relates more particularly to a spring clamp, therefore the subject matter of the present applicationis a'division of my original application Serial vNo. 625,873, filed May 8, 1911, and allowed December 12, 1912.

One object of the invention is to provide a cylindrical holder open along its side to form a channel and having arranged interiorly a plurality of spring clamps which may be locked in, openposition.

l/Vith this, and other objects in View, as will become more apparent as the description proceeds, the invention consists of certain novel features of construction, combination and arrangement of parts as will be hereinafter described, illustrated and claimed. V

In the accompanying drawings: Figure 1 is an end elevation of the file; Fig; 2 is a perspective view of one of the holders; Fig. 3 is a cross sectional view through one of the holders showinghthe clamp in closed position and showing the holder supported. a

by its sheath; Fig. 4 is a view similar'to Fig. 3 showing the clamp in open position; Fig. 5 is a section on line 00 00 of Fig. 3; Fig. 6 is a fragmentary plan view of one of the holders showing the clamping means.

The file includes a carrier frame 8- supported in any suitable manner and provided with a plurality of sheaths or guides 10, for supporting the drawing holders. The frame 8 is preferably made of sheet metal for the sake of lightness and cheapness and the sheaths or guides 10 may also be made of sheet metal in channel shape, said guides having inwardly extending flanges 11 at their lower edges to receive and support the drawing holders, Card holders 12 may be formed on the sheaths or guides 10 to receive cards or number tags 13.

The drawing holders 14 may be formed of sheet metal bent in cylindrical shape, open at the bottom to form a channel, the sides of the holder being formed with grooves 15 to receive and engage the inwardly extending flanges 11 of the guides H upwardly, so as to be engageable within a slot 22 1n the'top of the cylindrical holder,

the holder top being cut away, as shown at 23, in advance of this slot to enable the fingers to be inserted at each side of the upper arms ofthe clamps, so as to grip the said arms'for opening the clamps. A-bowspring 24: embracing the clamp jaws tends to press the said jaws together to grip the paper. The ends of the tube or cylindrical holder. 14 may be closed by disks 26, fastened, for example, by seaming the wall of the tube over the disk. These disks may be marked or numbered on the outside, in correspondence with the marks on members 13 in the sheaths or'guides' 10, as indicated at 13.

The file is used as follows: Assumingthat one of the holders 14 is removed from the carrier frame 8, the drawings are inserted in the holder by pressing on the handle portions 21 of the jaws 17, so as to separate the jaws, and then sliding said handle portions into the slots 22 in the holder, the walls of said slots then holding said handle portions close together and holding the jaws apart. One or more drawings, according to the capacity of the clamps and the requirements of the user are then inserted within the openingat the bottom of the cylindricalshaped holder 14 and within the open jaws 17 and the handle portions of the jaws 17 are then. drawn out of the slots 22 in the holders, allowing the springs 24 to close the jaws forcibly on the drawings and grip the drawings in the holder. The holder may then be slid endwise into one of the sheaths or guides lOon the carrier frames 8, the card 13 in the corresponding card holder 12 and the numbered tube end, indicating the classification of the drawings in that holder. If it is desired to remove, the drawings, the

corresponding holder will be slid out-from the guide 10 thereof and the set or bunch of drawings in the said holder may then be rolled up on the said cylindrical holder forming a base for a convenient package if same is to'be carried about; Any one or more of the'drawings insaid set can be removed by loosening one or both of the clamps. Thus, if it is desired to remove any one of the drawings while retaining the others in the holders, one of theclamps will clamp opened and the drawing then withdrawn bodily from the set, the second clamp being then closed leaving the set in position in the holder.

, WVhat I claim is: e V

"1. In a file for drawings, a drawing holder formed as a channel member open along the bottom, and clamps within the channel formed with jaws hinged together and extending downward from their hinge connections, and provided with handle means extending upwardly from the hinge connection of the jaws, and spring means tending to press the jaws together,,the top of the channel member being cutaway to expose said handle means.

holder formed as a channel member open along the bottom, and clamps within the channel formed with jaws hinged together and extending downward from their hinge connection, and provided with handle "means Copies of this patent may be obtained for 2. In a file for drawings, a drawing extending upwardly from the hinge connection of thejaws, and-spring means tending to press the jaws together, the top of the channel member being cut away to expose said handle means, and provided with slots for engaging said handle means, the jaws belng slidably mounted on the channel member to'move their handlemeans into and outv of said slots. r

3. In a file for drawings, a drawing holder moved endwise in one direction on the.

holder, and for releasing the clamps when they are moved in the opposite direction.

' 4.- In a file for drawings, a drawing holder having a slot, a clamp shiftably mounted to move into engagementwith the slot to hold theclamp open position,- and means tending tolclose 'theclamp when said clamp is disengaged from theislot' 5. In a file for drawings,ia drawing holder consisting of a. channel member provid'ed'with clamping means inside the channel for' detachably securing the drawings to the holder with the edges of the drawings extending within the holder, said holder beingflcylindric'al to adapt. it for holding the drawings thereon.

, Intestimony whereof, I have hereunto'set my" hand at Los Angeles, California, this NQ r,'1914. I r
